v Application filed September-27, 1923. 'Serial No.6 65,098.

To all whom it 'may concern:

Be it known that l, WILLIAM T; B-uRNs, a citizen of the United States, and a resi- 'dent of the city of Canton, in the county of Stark and State of Ghie, have invented a new and useful Improvement in Shattl-langer Bearings, of Which the following is a specification'. i

My'inventi ings of the ty e in which conical rollers are used as antifrctiontmembers and it has for its principal objects a simple and eflicient form of bearing, which can be used to replace the antifriction members of lshaft anger bearings now commonly used, that will hold a shaft against all ordinary endwise movement, but which will permit end-,

wise movement-under extraordinary stresses, that will accommodate a shaft that is'inaccurate in size or straightness, and that will prevent leakage of lubricant from the bearings.

Theinvention consists principally'in the i combination/with A`a banger box and shaft of a sleeve mounted on said shaft and secured thereto at the ends only and conical roller bearings interposed between the sleeve and the hangervbox. The invention further consists in the parts and combinations of parts hereinafter described and claimed.

ln the accompanying drawing,

Fig.4 l is a longitudinal Sectional View of a shaft hanger bearing embodying `*my invention; I f

Fig. 2 is an end View showing particularly one ofthe clamp rings that holds the sleeve v on the shaft; and

f Fig. 3 is a transverse Sectional view on the line 3--3 of Fig. l.

A shaft A extends through a banger box *B in the ends of which are mounted 'conical roller bearings C. The hanger box is lof reduced diameter in its middle or body portionl and is provided with projections 2 of 'i spherical shape that' cooperate with screws 3 having corresponding spherical shaped depressions 4: in the endsasaid screws being ;mountedin asuitable supporting member 5 whereby the hanger box is held in position. i Mounted on the shaft A is a sleeve D that is of slightly larger diameter than the shaft, so that the sleeve fits loosely on the shaft. The ends of the-sleeve'are provided with longitudinal slots 6 and are externally thr-ended. Mounted. on eaohthreaded porcn relates to shaft banger beartion ofthe sleeve is a split ring? that is nternally threaded to fit the threads of the vsleeve. The meeting ends of each split ring T are provided with lugs 8 that are secured together as by means of a screw 9 passing therethrough. The tightening of the screw 9 draws the ends of the rin 'Z towards each other and causes the ringto e clamped rmly on the sleeve B, thus drawing the sleeve tight on the shaft. Mounted on each screw 9 or otherwise secured between the ends of each ring is a locking 'plate 10 that fits into one. ofthe slots 6 in the sleeve, thus holding the proper adjustment of the sleeve and clamp rings, and holding the bearing cones in place. The cones 11 of the roller bearings C are mounted on the sleeve B adjacent to, the threaded portions and the clamp, rings 7 are provided with annular,, ,ribs 12 forming nuts that abut against the ends of the conesf The position of each vcone may be changed by moving theadjacent clamp ring 7 and nut portion 12 lengthwise of the sleeve. The cups 13 or outer bearing members are mounted in the ends of the banger box, suitable shoulders 14: being provided to form abutments therefor. The conical rollers 15 are interposed between'the cups and cones, said rollers being preferably provided with suitable cages 16.

rictlat ring 17 is secured in each endof the banger box as by a tubular extension 18; and a flat ring 19 is secured on the annular rib 12 of each clamp ring, as by a tubular extension 20. The two rings 17 and 19 'overlap and form a seal for the lubricant in the bearing. i i i The shaft is normally' held against endwise movement; but under extraordinary conditions, it may creep endwisethrouglh the sleeve. The sleeve fits loosely on t e shaft except at its end portions; andi'thus irregularities in the size or straightness of the shafteare accommodated. The sleeves are clamped to the shaft all around the circumference, instead of being held at one point by a set screw or the like and there is no tendency for the roller bearing assembly to run eccentric with relation to the shaft. The bearings may be adjusted and they are 'firmly secured in place. 'The antifriction lool [i Obviously, numerous changes may be made without departing from't-he invention and I do not wish to be limited to the precise construction shown. i VVhat lI claim is:

A bearing for shafting comprising a hanger box, a shaft extending therethrough, a sleeve mounted on said shaft, conical roller bearings interposed between said sleeve and 10 said hanger box, the ends of said sleeve being slotted lengthwise and being externally threaded, split rings threaded on to the ends of said sleeve, said rings having annular ribs abutting against the inne` bearing members of said conical roller bearings, and locking plates secured to said rings and each adapted to fit into a slot of said sleeve.
